Pollution Control (Compare Exercise 15.) The cost of controlling emissions at a firm is given by C(q) = 4,000 + 100q, where q is the reduction in emissions (in pounds of pollut- ant per day) and C is the daily cost to the firm (in dollars) of this reduction. Government clean-air subsidies amount to $500 per pound of pollutant removed. How many pounds of pollutant should the firm remove each day to minimize net cost (cost minus subsidy)?
